Can a flow integrator measure and display the temperature and pressure of the medium?

Can a flow integrator measure and display the temperature and pressure of the medium? Are its temperature compensation value and pressure compensation value the real-time temperature and pressure of the medium? How to switch the display mode, from showing flow rate to displaying temperature and pressure

It depends on what type of compensation method you are using and what kind of calculator you have. If you are using a calculator that accepts three different signals – temperature, pressure, and differential pressure – separately, then the calculator should have separate buttons for switching between the displays, or different areas on the display to show the data for each signal. If you are using a multi-parameter transmitter in which the instrument itself has built-in differential pressure, pressure, and temperature modules that carry out compensation functions on their own to output the compensated flow signal, then you need to first change the instrument’s output from single-channel to multi-channel, and specify the content, units, range, and other details for each channel of output. At the same time, the system or something else must also have channels to receive these signals. Of course, to carry out these operations, first the instrument must support multi-output functionality; additionally, some extra hardware may be required to enable the transition from single output to multiple outputs. If that’s what you want to see, some multi-parameter meters allow the display header to show multiple items, with updates done via polling and automatic switching every few seconds. I have done one elsewhere where users measure steam, and they need to be able to see the flow rate, pressure, differential pressure, temperature, and heat signal at the same time.

Sure, we have steam flow meters with temperature and pressure compensation; it is possible to choose between manual and automatic compensation for both temperature and pressure.

To perform temperature and pressure compensation, it is necessary to know the temperature and pressure at all times. The integrator can display parameters such as temperature, pressure, and instantaneous flow rate; you can try checking these values in the parameter section~~

This post was last edited by jmdc on 2017-10-18 at 08:08. The actual temperature is around 190°C, so why does the displayed temperature read 850? (Both accumulators show this value, so instrument failure can be ruled out.) The actual pressure is about 0.65 MPa (g), yet the displayed pressure is 0.605. What does “accumulation this time” refer to? “What about “time”? What is the reference point for temperature and pressure compensation? What does differential pressure of 130 refer to?

Go and check the instruction manual; Changhui, Pangu – many brands can do this

The temperature reading of 850 seems to indicate an open circuit; is 0.605 due to a different range setting? The cumulative value shown here is the cumulative value for this particular instance. Temperature and pressure compensation refers to the adjustment made to the flow rate when the temperature and pressure are not at the set values. A differential pressure of 130 means that the differential pressure is 130 kPa, which is quite high
